Abstract

Production of tetrafluoroethylene and hexafluoropropylene in very high combined selectivity by pyrolysis of chlorodifluoromethane, optionally using gaseous diluent wherein the pyrolysis is effected under substantially isothermal and uniform conditions, the reaction temperature is within the range 750-980 DEG C (preferably 800-980 DEG C), and the gaseous residence time is within the range 1 to 50 milliseconds. A fluid-phase electromagnetic induction reactor suitable for effecting the process is described.
